Definitions

  • This invention relates generally to a cam follower assembly for actuating a reciprocating movement used in automotive or industrial applications such as fuel injection pumps, ICE valve timing systems for internal combustion engines, valve train cam followers or rocker arm bearings.
  • Engine manufacturers strive to improve performance of internal combustion engines by maximizing the conversion of chemical energy to mechanical energy.
  • the conversion efficiency may be improved when losses of energy used to overcome friction between moving parts in the engine are reduced.
  • Mechanical design along with oil and other lubricants aid in reducing these losses.
  • cam followers In particular cam followers for actuating high-pressure fuel pumps, have significantly increased.
  • the load applied on the cam follower devices is increased proportionally.
  • Roller follower assemblies are mechanical design improvements that reduce friction losses between a cam and a rocker arm.
  • Past systems used a sliding contact between the cam and rocker arm. These systems resulted in large frictional losses. Also, these systems experienced increased wear. Roller follower assemblies reduce friction between the cam and rocker arm by changing the sliding contact to a rolling contact. However, roller follower assemblies may still have a problem with wear.
  • Each roller rotates about an axle shaft.
  • oil reduces sliding friction between a roller and the axle shaft, wherein the lubricating oil is usually provided with a constant flow rate while the engine is operating.
  • the assembly has to be operative even in transitory periods where the oil flow is interrupted or has not yet started, e.g. when the engine is started and the future trend might even go towards completely oil-free operation.
  • the present invention seeks to provide a cam follower assembly meeting the above requirements. This object is achieved by a cam follower according to claim 1, wherein preferable embodiments of the invention are defined in the dependent claims.
  • the invention starts from a cam follower roller assembly comprising a body, a shaft mounted on the body, and a roller rotatably mounted on said shaft, wherein at least a radially outer surface of the shaft and/or at least a radially inner surface of a bore of the roller are coated with an antifriction and/or wear resistance coating.
  • said antifriction and/or wear resistance coating comprises tungsten (IV) sulfide (WS2).
  • Tungsten (IV) sulfide (WS 2 ) is a solid lubricant which despite being in the solid phase, is able to reduce friction between two surfaces sliding against each other without the need for a large amount of liquid lubrication medium.
  • the dry lubrication is sufficient to ensure a reliable and non-damaging operation even in initial phases when no oil flow is provided.
  • the provision of tungsten (IV) sulfide (WS2) reduces the required minimum oil flow rate strongly even in continuous operation.
  • the dry lubricant is entirely formed by tungsten (IV) sulfide (WS 2 ) crystallites, which is sometimes referred to as tungsten disulfide.
  • the antifriction and/or wear resistance coating is a layered structure of flat crystals, wherein spaces between the layers may be filled with lubricant.
  • the high pressure/load acting on the assembly may press the lubricant out of the pores or spaces and thus improves the lubrication.
  • the tungsten (IV) sulfide (WS 2 ) crystals have a crystal diameter of 0.8-1.5 ⁇ m and a thickness of 100nm or less.
  • the thickness of the antifriction and/or wear resistance coating is between 0.5 and 0.8 ⁇ m.
  • Alternative embodiments of the invention relate to cam followers further comprising a bushing radially interposed between the roller and the shaft.
  • two pairs of contact surfaces are formed, i.e. a first contact between the radially outer surface of the shaft and the radially inner surface of the bore of the bushing and a second contact between the radially outer surface of the bushing and a radially inner surface of a bore of the roller.
  • each of the pairs of contact surfaces defined above includes at least one WS 2 coating.
  • one of the a radially outer surface of the shaft, the radially inner surface of a bore of the roller or one of the radially outer or inner surfaces of the bushing is coated with the coating comprising WS2, wherein the surface being in contact with the surface coated with the coating comprising WS2 is coated with a diamond like carbon (DLC) coating.
  • DLC diamond like carbon
  • Fig. 1 shows a cam follower roller assembly 10 according to a first embodiment of the invention.
  • the cam follower roller assembly 10 may be used e.g. for actuating a fuel injection pump of an internal combustion machine.
  • the cam follower roller assembly comprises a body 12, a shaft 14 mounted on the body 12, and a roller 16 rotatably mounted on a radially outer surface 14b of the shaft 14.
  • a radially outer surface 14b of the shaft 14 and a radially inner surface 16a of a bore of the roller 16 are in contact with one another.
  • a radially outer surface of the roller 16 is adapted to be pressed against a cam provided on an engine camshaft (not shown) with a rotation axis parallel to an axis 14a of the shaft 14 and a rotation axis of the roller 16.
  • the body 12 has a roughly cylindrical form adapted to reciprocate in a guiding bore and is provided with a recess for receiving the roller 16.
  • the radially outer surface 14b of the shaft 14 is coated an antifriction coating.
  • the antifriction coating may be provided on the radially inner surface 16a of the bore of the roller 16 or on both the radially outer surface 14b of the shaft 14 and a radially inner surface 16a of a bore of the roller 16.
  • the bore of the roller 16 is fitted over the shaft 14 and the radially inner surface 16a of the bore, which is uncoated in this embodiment but which may be coated with an antifriction and/or wear resistance coating such as the coating on the shaft 14 or such as a DLC coating on other embodiments of the invention.
  • the antifriction and/or wear resistance coating comprises tungsten (IV) sulfide (WS2).
  • the dry lubricant is entirely formed by tungsten (IV) sulfide (WS 2 ), which is sometimes referred to as tungsten disulfide.
  • the WS 2 coating is a layered structure of flat tungsten (IV) sulfide crystals, wherein spaces between the layers are filled with lubricating oil during operation.
  • the high pressure/load acting on the assembly may press the lubricant out of the pores or spaces and thus improves the lubrication.
